Trevor Lawrence underwent surgery on his left (non-throwing) shoulder Tuesday in California.

Lawrence, widely expected to be the No. 1 overall pick by the Jacksonville Jaguars, can start throwing in four to six weeks and is expected to be ready for training camp, according to a source.

The procedure, performed by Dr. Neal ElAttrache, was to repair damage to the labrum in his left shoulder.

Trevor Lawrence had an impressive pro day workout on Friday, further solidifying his position as the No. 1 pick.

"The original plan was to have two months training out in California, then come back March 11th and put on a show and do all that, but life happens sometimes," Lawrence said on the ACC Network/ESPN2 following his 45-minute workout at Clemson on Friday. "Just having to adjust and showing I'm able to adjust and adapt and still willing to come out here and throw and give teams a chance to see me, that was important to me and important to my team to make sure we made that happen.

"Obviously it wasn't necessarily the ideal situation and circumstances, but I think we did a great job of just kind of maneuvering and navigating through all that."

Thirty-one people from 17 NFL teams were scheduled to attend the workout, including three from the Jacksonville Jaguars: head coach Urban Meyer, offensive coordinator Darrell Bevell and passing game coordinator Brian Schottenheimer.

Trevor Lawrence will throw for NFL teams on February 12th instead of participating in Clemson's scheduled pro day next month.

Lawrence will undergo surgery to repair the labrum in his left shoulder after that workout.

Lawrence is expected to be recovered for the start of training camp.

The Jacksonville Jaguars are widely expected to select Lawrence first overall.
